Description: Urbanization is a global phenomenon that has transformed and continues to alter landscapes and the ways in which societies function and develop. For this issue of UGEC Viewpoints, the editors collected case-studies presented at the Open Meeting that span across regions and themes: from Australia and the United States, as well as the less developed nations in Africa, megacities of Asia such as Dhaka, Bangladesh and Delhi, India, vulnerable coastal areas of the Yucatan Peninsula, and the largest rainforest in the world, the Brazilian Amazon.
